antidromic conduction

antidromic conduction

[an′tidrom′ik]

Etymology: Gk, anti + dromos, course

the conduction of a neural impulse backward from a receptor in the midportion of an axon. It is an unnatural phenomenon and may be produced experimentally. Because synaptic junctions allow conduction in one direction only, backward, antidromic impulses fail to pass the synapse, dying at that point. Compare orthodromic conduction.
